The Lowdown
Alright, Rusty here again. Let’s break it down in feet. Only one spot on the radar: Jaconé.
Water temp is about 73°, just a touch warmer than average for this time of year. Tuesday, August 4th, kicks off small – morning has 2ft east swell with a clean light offshore, but the period is a short 8 seconds and the energy is weak (162). The afternoon goes flat and cross-offshore. Not much going on.
Things improve Wednesday the 5th. Morning brings 3ft southerly groundswell at 12 seconds, clean with a light offshore. Energy jumps to 646. This is the best of the first few days. Thursday the 6th has 5ft from the ENE but only 7 seconds, so it’s a bit lumpy and weak.
The real goods come Friday, August 14th. Morning has 8ft of southerly groundswell at 14 seconds, with a light offshore breeze. Energy is 2633 – that’s powerful. At 8ft, this is expert-only territory. Glassy, heavy, and long-period. The break is a beach, so with that period it might be a bit straight, but it’s your best chance for a proper session. That’s the standout.
Saturday the 15th morning is glassy with 6ft south swell at 13 seconds, energy still strong at 933. Another great session.
After that, it drops off. Sunday the 16th is 4ft with offshore, then the following week turns onshore and messy. Wednesday the 19th afternoon shows 8ft from the SSW but at only 8 seconds – sloppy under moderate cross-offshore wind. Skip it.
Circle August 14th. That’s the one.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
